### TITLE: HYDRAULIC POWER - GREEN AUXILIARY HYDRAULIC POWER ((RAM AIR TURBINE)) - RAT PUMP HEX SHAFT MODIFICATION **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR None MINOR 202537D50553 NOTE: As per EASA IR 21, a minor change is one that has no appreciable effect on the mass, balance, structural strength, reliability, operational characteristics affecting the airworthiness of the product. All other changes are major changes. REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES During the AIRBUS production flight test of an A330-300 aircraft, the Ram Air Turbine (RAT) did not pressurize the green hydraulic system. Investigation revealed that the impeller drive (hex) shaft had a reduced length of engagement with the pump drive shaft. This caused the impeller drive shaft to disengage from the pump and disconnect the impeller. It was determined that the root cause of the disconnection was the internal hex dimensions on the pump impeller shaft had been changed in a supplier drawing in October 2007. This Service Bulletin is published to advise all operators of A340-200/300 aircraft of the issue of HAMILTON SUNDSTRAND Service Bulletin ERPS06M-29-19. This introduces an inspection to the RAT hydraulic pump via serial numbers to ensure that all suspect RAT hydraulic pumps are captured. If the RAT pump is suspected, It also outlines the modification to the RAT hydraulic pump by the installation of a new hex drive shaft with an increased hex socket length and an increased internal hex depth. This Service Bulletin installs a new impeller drive shaft that is match sized in the retrofit process of the pump to ensure a minimum engagement of the hex drive shaft to eliminate the possibility of impeller disengagement. The incorporation of this modification will provide improved reliability of the RAT.
